Abstract (en)
[origin: WO2007100258A1] A method and a device for use in calibrating a projector image display towards a display screen, wherein the display screen is equipped with a plurality of discrete light detection points on or in the front surface of the screen, or located immediately below the front surface, wherein each light detection point or groups thereof are associated with a light detector, wherein at least one image is projected towards the display screen, and wherein it is determined which image pixel or pixels of the projected image hit the respective detection point on the screen, and/or wherein brightness and/or colours in the projected image are correlated by comparing measurements at the detection points and relevant projector parameters are adjusted correspondingly.
